My invention relates to improvements in portable commodes, and itconsists in the constructions, combinations and arrangements hereindescribed and claimed.

An object of my invention is to provide a portable commode, having asone of the principal features, a pedal-operated lid so arranged withrelation to a pull-bar, that the lid is braced when open forming a restfor the back of the user.

Another object of the invention is to provide .a portable commodeincluding footoperated link and pull-bar devices which are adapted toraise a lid upon being depressed by the foot of the user. a spring beingembodied to return the parts to a normal position when foot pressure isreleased, thus automatically tightly closing the lid.

Another ob ect of the invention is to provide a lid strap curved toavoid the lid hinge and at the same time form an abutment for restingagainst an extension of a pull-bar above, the pivotal point of the lidstrap to the pull-bar, to form a brace for the lid when it is open.

Other objects and advantages will appear in the. followingspecification, reference being had to the accompanying drawing in which:

Figure 1 is a central vertical section of (portable commode showing thelid close Fig. 2 is a side elevation of the ortable commode showing'howthe operating link devices are concealed from view, and

Fig. 3 is a detail sectional view showing how the curved portion of thelid strap rests against the extension of the pull-bar to brace the lidwhen open.

In carrying out my invention I provide the receptacle 1 which issuitably shaped to present an attractive appearance. The receptacle 1hasa bottom 2 arranged-at the required distance from the top or seat 3.It will be observed that the seat 3 is suitably rounded, while the frontportion of Specification 01 Letters Patent.

Application filed July 21, 1917. Serial No. 182,509.

be observed in Fig. 2 that the treadle 8 is the only visible part of thelid operating mechanism, the lid operating mechanism being concealed inthe bottom of the commode.

The treadle 8 is pivoted to a lever 9 which is S-shaped and is fulcrumedin the middle to a bracket 10 fixed on the bottom 2 as clearly shown inFig. 1. The bar 7 of the treadle 8 is fulcrumed on a bracket 11 alsofixed on the bottom 2. The rear end of the S-shaped lever 9 is pivotedto a short arm. 12 of a pull-bar 13. .The short arm 12 moves in the slot6 at the rear of the receptacle 1.

A spring 14 connected at its ends respectively to the bottom 2 and theS-shaped lever 9, pulls the rear part of the lever 9 up thus keeping thetreadle 8 in an elevated position, and also keeping the lid of thereceptacle tightly closed.

The lid 15 of the receptacle is hinged at 16 to the receptacle. The rimof the lid is properly shaped to conform to the shape of the seat 3thereby snugly fitting the seat and maintaining a tight closure of thereceptacle.

The pull-bar 13 has an extension 17 above the pivotal point 18 of a lidstrap 19. This construction is clearly shown in Fig. 3, wherein it willbe seen the lid strap 19 is curved at its free end at 20. The extremeend of the lid strap 19 adjacent to the curved free end 20, is curled at21 to form a hinge at the point 18.

It will readily be understood from Fig. 3 that one of the two-foldfunctions of the curved end 20, is to avoid the hinge16 of the lid, andtheother is, to act as an abutment for the lid against the extension 17of the pull-bar 13 thus bracing the lid when it is open and form a backrest.

as is also the bottom of the receptacle, thus access to the workingparts may readily be had, for'oiling and repairing the mechanism.

The operat on of the device is as follows. i

The treadle 8 normally assumes the elevatedposition shown in Fig. 1. Thetreadle 8 is shown at an inclination with respect to the receptacle 1,but obviously it may be arranged in other relationships. The treadle 8is depressed by the foot of the user, when the S-shaped lever 9 willrock on its fulcrum pulling the pull-bar 13 down.

7 an abutment for the curved end 20 of the lid and thus braces the lid.

While the construction and arrangement j of the device is that of agenerally preferred form, obviously modifications may be made withoutdeparting from the spirit of the invention or the scope of the claims.

I claimz .1. In a portable commode, "thecombination of the receptaclehavin a lid hinged pull-bar having an extension, and a lid strap securedto the lid and fulcrumed to. the pull-bar at the base of theextension-,the

lid strap being shaped to avoid the hinge and engage the extension whenthe lid is open and brace the lid.

2. A portable commode comprising are} i ceptacle having a shield at theback and in cluding a bottom, the receptacle formed with a houslngbeneath the bottom, a treadle fulcrumed 1n the housing and protruding atthe front, a lever fulcrumed in the housing land pivoted to the treadle,means connected to the lever for holding the treadle in its brace forthe lid, and a handle for the reto said cover and projectingtherebeyond, a

pull bar. havingan extension, said lid strap 7 I beingpivotallyconnectedto said pull bar at a pomt below and at one'side ofsaid extension, and means for-drawing said pull bar downwardly therebswinging said cover upwardly whereby sald strap will engage saldthereon, a'pull-bar for operating the lid, said extension for limitingthe movement of said cover inone direction- 1 In testimony whereofIafiix my signature in presence of two witnesses.
